Answer: 7 and 1/2

Step-by-step explanation:

First convert both parts to improper fractions. 4 *2 + 1 =9 so we have 9/2 ÷ 3/5. Dividing by a fraction is the same as mtiplying by its reciprocal (swapping the top and bottom numbers) so we have 9/2 x 5/3. Multiplying fractions multiplies the top and bottom together so we get 45/6. 6 fits into 45 7 times with 3 left over so we get 7 3/6. 3 and 6 are both multiples of 3 so we can simplify by dividing both of them by 3 so we get our answer 7 and 1/2.
